The event is open to all, with Mr Pratzky saying, "If you breathe air, if you drink water and if you eat food, then you are a friend of Dayne's".

As part of the "A Concert in the Gaslands", Ash Grunwald, activist Jarmbi'je Githabul and Mr Pratzky will hop aboard surfboards to "surf the bubbling waters of the Condamine River" wearing gas masks.

The stunt is designed to "draw attention to the destructive impacts of fracking" and its impact on the water system, according to organisers.

Organisers expect messages of support from well-known Australians including Bob Brown, Jack Thompson, John Williamson, Xavier Rudd, John Butler and Leo Sayer.

The region is a contentious battleground for landholders, environmentalists and the gas industry, with many in the area reporting health impacts they attribute to gas exploration and extraction.

The gas industry has denied there are any health impacts.

A study by the Queensland Government published in January specifically addressed concerns about the bubbling of the Condamine, finding it to be no threat to health and caused by the natural occurring gas in the ground.

The event is slated to run from noon until 10pm on Saturday July 13 at 218 Old Tara Road, Wieambilla, about two and a half hours drive west of Toowoomba.
